ADDING AND REGISTERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 510,927, dated December 19, 1893.

Application filed February 23, 1893. Serial NOASSAI, (No modell To @ZZ whom t may concern:

Be it known that I, VILLIAM A. NEAL, a citizen of the United States, residing at Bungers, in the county of Greenbrier and State of Test Virginia, have invented a new and useful Adding and Registering Machine, of which the following is a specification.

My invention relates to an improved adding and registering machine, the objects in view being to provide a simple, cheap and effective device for adding successive numbers, as amounts of sales, zc.

It is the primary object of my invention to provide a device which, being accurate in operation, is free from complex construction,

may be easily understood and readily operated.

Further objects of my invention will appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.

In the drawingsz-Figure 1 is a plan view of a machine embodying my invention, with all the parts set at zero. Fig. 2 is a similar view with the parts set to register a sum of iive thousand two hundred and eighty. Fig. 3 is a central sectional view of the machine, line 3 3 of Fig. l. Fig. at is a similar view, line 4 4 of Fig. l.

The same letters refer to the same or corresponding parts throughout the several views.

A designates the base, provided with a central circular depression or cavity B surrounded bya guard-ring C, andD designates a central perpendicular arbor from the upper end of which to a point outside the circnmference of the depression B extends a radial gage-bar E, provided with terminal point or points, c, to engage aslot, @Qin the guideplate V', to hold the outer end of the gagebar fromlateral displacement. Mounted centrally upon the arbor and arranged in the depression or cavity B below the plane of the upper surface ofthe base is a rotary disk F whose serrated periphery f rests upon an annular bearing rim F.

G designates a superposed fixed dial, of less diameter than the disk F, with its periphery on the line of the bases of the serrations in the latter, and inscribed with nnmerals from O to 99, the intervals between such numerals corresponding with the intervals between the serrations f. The disk F is also provided, (see Figs. l and 2,) beneath the dial G, with a corresponding series of numerals ranging from O to 99. Said disk is provided with one hundred teeth.

Rotatably mounted upon the arbor D and resting upon the dial G is a smaller disk H, also provided with peripheral serrations h which are numbered from 0 to 99, (see Figs. l and 2,) and arranged above this disk is a smaller fixed plate K which covers the numerals upon the disk H.

The dial G is held from rotation by the gage-bar E, which is provided with a depending lug c to engage a perforation c therein, and this dial is also provided with a notch g through which one numeral of the disk F may be seen.

Atiixed to the underside of the disk F is a sprin g tongue T, provided at its free end with a pin t which projects vertically upward through a perforation t in said disk when the free end of the tongue is elevated and which is normally held out of engagement with said perforation by the spring. A cam U is arranged in the depression or cavity B adjacent to the gage-bar E whereby when the disk F has been turned through a complete rotation the free end of the tongue T engages the cam and is elevated thereby and the pin t is caused to engage a tooth of the rotatable disk H. The dial G is slotted as shown at g to allow the pin t to project upward to engage the teeth of the disk H.

The plate K is held from rotation at all times byastop-pinc, which engages the gagebar E, and it is provided, adjacent to Such pin with a notch 7e through which may be seen one of the numerals upon the disk H.

The disk F is the units-disk, and as one complete rotation of said units-disk causes the disk H to move through the distance of one tooth (caused by the engagement therewith of the spring actuated pin t) the disk H will be designated the hundreds-disk.

The plate K is provided with an opening 7c, and pivotally connected to the under side of said plate by the pivot Z, in position to canse a portion of its surface to be visible through the opening la is a thousands-disk L, whose upper surface is provided with numerals ranging from O to 14 and correspond- IOO ing respectively with the peripheral teeth L', fifteen `of which are provided. The thousands-disk is operated by a pin or stud h carried by the hundreds-disk H to engage a tooth of such thousands-disk and move the latter through the distance ofone tooth for each complete rotation of the hundreds-disk. It will be seen that the highest amount which can be registered upon the hundredsdisk is ninety-nine hundred, and therefore, when'the units disk has been turned through an entire rotation and indicates ninety-nine, thus making the total ninethousand nine hundred and ninety-nine, the movement of the units-disk through the distance of one space will turn the hundredsdisk through the distance of one space and thus rotate the thousands-disk through the distance of one space, whereby the thousands-disk, 'which registers tens of thousands, will stand atl, and the hundreds and units diskswill -stand at O, thus registering ten thousand.

Rotatably mounted upon the arbor D above the plate 'K is a fractionsdisk M, andabove the latter is arranged va fixed dial N, whose surface is inscribed with fractions ranging from one thirty-second to thirty-one thirtyv seconds, with intermediate fractions, as onesixteenth, one-tenth, one-eighth, one-seventh,`

one-fifth, one-third, one-half, &c., o'frdifferent denominations, and also a pointmarked zero.j Above the dial N is arrangedy a rotatable plate O, which is connected by an arm P seey Figs. l and 2 to the periphery of the disk Ml to rotate therewith, said plate beingprovided; i

fractions has amounted to a unit, the disk P will y'be turned to indicate suchunit.

The arbor D is screw-threaded, as shown, and the disks are held in the required relative positions by nuts S S and washers S S.

The operation of my improved machine will be apparent from the foregoing description without employing examples. The gage-bar is employed as the stopping point, and to this bar all of the disks are turned in adding successive numbers. A longitudinally slidable catch V is arranged in a slot formed in the guide-plate V upon the base in position to engage onev of the teeth of the disk F to lock said disk in position to preserve the adjustment thereof to indicate a certain r`sum vor amount registered.

Changes inthe form, proportion and minor details' of construction -may be `vresorted v`to without departing from the spiritpf theinl vention or sa'crifibing anyv of the*v advantages thereof. v

lHavingthifis described my inwentiomwhat I claim, 'andl` desire `to securev by *Letters fPatent of the United'States,fis
